Actually Len, I would consider this a pretty good log. To me PE Mode/WOT fueling look pretty good. .96-.98 Bens are pretty good!
I did get some high areas in the ve after this log, even with the tight filter. (95kpa 4400 rpm to 6800 rpm) I smoothed them out a bit and blended the area around them. The values are not quite as high as my 98 tune in those areas. (havent done alot of wot, just this log)
The VE Values actually looks pretty legitimate. Based on your MAF Flow, they appear to be quite reasonable. VE Values normally peak around 4800-5200 Rpm and slowly fall off.
How will the VE being off in the upper range affect the maf calibration. I dont want fine tune the maf, and mask a ve issue, (if in another log or two it doesnt change much.) The selbens seemed pretty close this go round. It did lean them up a bit.
To my eye, your VE Values appear to be within 4% of what I would compute them to be. You are pushing over 420 g/s of air. Your VE Values should be ~ 110%. So if it off a couple of percents, it will have NO affect on the MAF..I.E., you are doing everything correct!
